Hi, thanks for that, for some reason I just assumed I would need a push-on cap, but anything other than a painfully slow to remove screw-on cap would do nicely. I'll try one whe I get home.

Regards,

It's a 49mm screw in IIRC, screws into the filter thread.

It's a Ricoh "PK-AR" mount:

The hazard from the infamous Ricoh "pin" is very real. There are two variants of the "pin". One is a rigid, retractable pin and the other is a spring-loaded ball. Both are located such that they will "fall" into the AF slot drive on the camera body causing the lens to jam on to the mount. The ball type can be fairly easily wiggled out of the AF slot. The pin type is much more difficult.

The lens may be modified and made safe by disassembling the mount to remove the pin.

Thanks Mat, I have the Teleplus MC7 (non DG) I keep meaning to try it on the Tamron 90mm Di, The Tamron 1.4x works well with the 90mm, now the MC7 is definitely on my "to do" list

The DFA100 performs well with the 2x TC, could I ask which TC.

John

Nice set David, well worth a visit IMHO.

John

Are you sure? The built in sliding lens hood would seem to interfere, I'm surprised nobody makes a 3rd party one.

John

Lovely set Mat, I've never seen a white headed duck before.

John

Really like #5 BTW

John

Nice, congratulations. You're gonna love the DA*300
